Mount the QFX5100-96S

The QFX5100-96S can be mounted in either a two or four-post rack configuration. For two-post installation instruction,
see the QFX5100 documentation at https://www.juniper.net/documentation/product/en_US/qfx5100. To mount the
device in a 19 inch rack:

1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.

NOTE: If you are mounting multiple units in the rack, mount the heaviest unit at the bottom and mount the

others from bottom to top in order of decreasing weight. The switch weighs approximately 32 lb (14.5kg).
Installing the QFX5100-96 switch in a rack or cabinet requires two people to lift the switch and secure it to
the rack.

2. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the
building structure.

3. Determine whether the end with field replaceable units (FRUs) or the ports are to be placed at the front of the rack.

4. Align a front mounting-rail (either flush with the front of the chassis or 2-in. recessed from the front) along the side
panel of the switch chassis.

5. Attach the mounting rail to the switch using six mounting screws. Use cage nuts and washers if your rack requires
them.

6. Repeat Step 4 and Step 5 on the opposite side of the switch.

7. Have one person grasp both sides of the switch, lift it, and position it in the rack so that the front bracket is aligned
with the rack holes.

8. Have a second person secure the front of the switch to the rack using four mounting screws (and cage nuts and washers
if your rack requires them.) Tighten the screws.

9. Continue to support the switch while sliding the rear mounting-blades into the channel of the side mounting-rails and
securing the blades to the rack. Use the four mounting screws (and cage nuts and washers if your rack requires them)
to attach each blade to the rack. Tighten the screws.

10. Ensure that the switch chassis is level by verifying that all the screws on the front of the rack are aligned with the
screws at the back of the rack.

11. Attach a grounding cable to earth ground and then attach it to the chassis grounding points.

Connect Power to the Switch

The switch is supplied with two factory-installed power supplies.

Connecting QFX5100-96S to AC power

To connect power to an AC-powered switch:

1. If the AC power source outlet has a power switch, set it to the OFF (0) position.

2. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate.

3. Push the power cord retainer onto the power cord.

4. Insert the power cord plug into the power source outlet.

5. If the AC power source outlet has a power switch, set it to the ON (|) position.

6. Verify that the AC and the DC LEDs are lit green and on steadily.
